Definitions
- the present invention relates to an apparatus for inhaling a substance, for example an apparatus for smoking.
- the electronic cigarette (or e-cigarette), sometimes called a vapoteuse or personal vaporizer, is an electromechanical or electronic device that generates an aerosol intended to be inhaled.
- This aerosol or “vapor” or even “artificial smoke” visually resembles the smoke produced by the combustion of tobacco.
- This vapor may or may not be flavored (tobacco, fruit aroma, etc.) and may or may not contain nicotine.
- the technology mainly marketed for electronic cigarettes is the technology of atomization or aerosolization consisting in the conversion of a substance in the form of particles small and light enough to be transported in the air, that is - that is to say in aerosol.
- atomization or aerosolization consists of the action of dispersing a liquid into fine droplets.
- the technology mainly marketed for electronic cigarettes is based on the use of a heating resistance to atomize or aerosolize a liquid. Concretely, the principle of such an electronic cigarette consists in producing an aerosol imitating tobacco smoke.
- the technique consists of heating a liquid (called liquid to be vaped) via a heating resistance: the user must activate the heating of the resistance, the liquid heats, vaporizes and condenses almost immediately in the form of fine droplets to produce an aerosol which the user can then inhale.
- the heating of the resistance can be activated either manually (for example by means of a switch) or automatic (for example by means of an electromechanical device detecting the aspiration of the user and then activating the resistance).
- a device for inhaling a substance for example an electronic cigarette, relying on the heating of a liquid generally consists of the following main elements: a battery (which powers the atomizer), an atomizer (which contains a resistance which will vaporize the liquid), a reservoir (the container of liquid) and a mouthpiece that allows you to inhale / inhale the vapor (aerosol) coming out of the atomizer.
- a battery which powers the atomizer
- an atomizer which contains a resistance which will vaporize the liquid
- a reservoir the container of liquid
- a mouthpiece that allows you to inhale / inhale the vapor (aerosol) coming out of the atomizer.
- an electronic power module a voltage variator, a temperature controller, a counter for the number of puffs
- means of communication with an electronic device such as for example a computer or a smartphone or any other device such as a charging device.
- the essential element of current devices for inhaling a substance, for example current electronic cigarettes, based on the heating of a liquid is the atomizer comprising a resistance which is the part having the function of heating to high temperatures of at least one. minus 190 ° C (generally between 188 and 290 ° C) the liquid in order to generate the aerosol.
- atomizers generally contain a resistive wire which surrounds a wick which may for example be made of silica fiber or of cotton and / or which is surrounded by a wad.
- the function of the wick or filler is to store the liquid and to bring it by capillary action to the resistance so that it is heated and vaporized.
- the atomizer and the cartridge are inseparable and form a single component, the latter is called “cartomizer” or cartridge with integrated atomizer.
- Cartomizers supply the atomizer with liquid through a wad.
- the power is supplied using a wick system, we speak of a “clearomizer”.
- the atomizers mainly used for heating are consumables whose lifespan varies enormously depending on the model, use and type of liquid.
- the liquid to be heated contains the following components: - a mixture based on propylene glycol (PG) and / or vegetable glycerin (also called glycerol, VG), optionally added to a combination of ethanol and / or water ( ⁇ 5%);
- PG propylene glycol
- VG vegetable glycerin
- liquids based on PG and / or VG are largely in the majority, a few alternatives do exist.
- propane-1, 3-diol or polyethylene glycol in its form of PEG400 are largely in the majority, a few alternatives do exist.
- devices for inhaling a substance, in particular electronic cigarettes, based on heating a liquid comprising aromatic substances are therefore not free from toxic products, in particular solvents and volatile organic compounds (VOCs) nor potentially carcinogenic toxic compounds, such as formaldehydes-hemiketals, acrylonitrile, acrolein, propylene oxide and acrylamide.
- VOCs volatile organic compounds
- propylene glycol and glycerin almost systematically used to maintain in liquid form the products of devices for inhaling a substance, in particular electronic cigarettes, are considered to be safe at room temperature but, when heated, produce compounds. potentially carcinogenic toxicants inhaled / inhaled by the user.
- devices for inhaling a substance for example smoking devices and in particular electronic cigarettes, relying on heating a liquid in order to generate an aerosol, require the presence of a battery, essentially to power the heating element. in electricity (usually a resistance).
- a battery in electricity (usually a resistance).
- any battery has a limited autonomy, this all the more so when its size and weight are reduced in order to be able to be integrated into devices for inhaling a substance, for example in devices for smoking.
- devices for inhaling such a substance for example smoking devices
- devices for inhaling such a substance include an atomizer of the mist or nebulizer type and a compressed air cartridge. While such devices for inhaling a substance, for example smoking devices, are functional, they nevertheless have certain drawbacks, the main one of which is that once the compressed air cartridge is empty, the device for inhaling a substance no longer exists. 'is no longer operational until this cartridge is replaced.
- a device for inhaling a substance for example a device for smoking “imitating” the smoke of a conventional cigarette obtained by combustion of tobacco, optimized at least partially solving the problems mentioned above, optionally and preferably by minimizing or even eliminating the problem relating to the presence of carcinogenic and toxic molecules generated inter alia by heating to high temperatures.
